WARP-STOP-MOTION CLAMP.

Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed June 3, 1920. Serial No 386,288.

To all whom it mayconcern Be it known that I, JOHN REGAN, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Warp-Stop-Motion Clamp, of which the following is a specification.

This invention relates to a clamp or holding device for a warp stop motion of the type in which a number of longitudinally extending bars are used, such as are shown in myprior Patent No. 1,265,112, issued May 7, 1918.

When such warp stop motions are used in broad looms, it is advisable to provide some form of clamp or support at one or more intermediate points to prevent vibration and to hold the parts in operative relation.

It is the object of my invention to improve and simplify the construction of such clamps, at the same time reducing the cost of manufacture.

More specifically my invention relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

preferred form of my invention is shown in the drawings in which- Figure 1 is a side elevation of my improved clamp, certain parts being broken away;

Fig. 2 is a sectional plan view taken along the line 22 in Fig. 1;

Fig. 3 is a top plan view of the device;

Figs. 4: and 5 are end elevations looking in the direction of the arrows 4 and 5 in Fig. 1, and

Fig. 6 is a along the line 6-6 in Fig. 1.

Referring to the drawings, I have shown a plurality of separator bars 10 and guide bars 11, such as are found in my prior patent previously noted.

My improved clamp consists of three simple pieces of metal, namely, a plate 12, a binding rod 18, and a cross bar 14:.

The plate 12 is preferably stamped from heavy sheet metal and is provided with notches or recesses and 16, to receive the separator bars 10 and vibrator bars 11 respectively. The binding rod 13 underlies the separator bars 10, and is provided with threaded up-turned ends fitting against the detail sectional view taken 4 ends of the plate 12. The cross piece 141s also preferably formed of a single piece of sheet metal, bent to the U-shaped section shown in Fig. 6, and fitting over the upper edge of the plate 12.

At its two ends the cross bar 14 is slotted to permit free passage of the ends of the rod 13. The slot at one end of the cross bar is closed as shown in Fig. 5, while the slot at the opposite end is open as shown in Fig. 4.

Binding nuts 17 onthe threaded ends of the bar. 13 constitute means for forcing the bar 1 1 against the plate 12 and securely holding the parts in position.

When the nuts 17 are loosened, the cross bar 14 may be slipped endwise, so that its open end will be disengaged from the binding rod 13. The cross bar may then be swung around the'opposite end of the rod 13 as a pivot and all parts of the device may then be removed from the stop motion if desired.

I have thus provided a clamp of simple construction, embodying very few parts which are all easy to manufacture. The device is found satisfactory and efficient for the purpose for which it is designed.

Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art, withinthe spirit and scope of my invention as set forth'in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1. A clamp for a warp stop motion, comprising a spacing member, a continuous rod inclosing said member on three sides, a cross bar fitting over the top of said spacing member, and means to bind said parts together.

2. A clamp for a warp stop motion having a plurality of longitudinally extending separator bars and vibrator bars, comprising a rigid plate recessed to receive said several bars, a continuous binding rod inclos1ng sald plate on three sides, a cross bar, and means on said rod to seat said cross bar against the upper edge of said plate.

section pivoted on said rod and resting on said plate, and binding nuts for said cross bar threaded on the up-turned ends of said rod.

4. A clamp for a warp stop motion having a plurality of lon 'itudinally extending separator bars and vi rator bars, comprising a rigid plate recessed to receive said several bars and supported by said separator bars, a wire rod underlying said bars and having threaded portions extending upward along the two ends of said plate, a cross bar formed of one piece of sheet metal bent to fit over the upper ed eof said plate, and means to bind. all of sai parts together, said cross bar being slottediat each end to receive the ends of said wire rod, one slot being open and the other closed at its outer end.

' In testimony whereof I have hereunto aflixed my signature.

JOHN REGAN.
